At a temperature of 70°C, methanol would be in a gaseous state while ethanol would still remain in its liquid state. Since the boiling point of methanol is lower than that of ethanol, it would boil off before ethanol. Therefore, at 70°C, you would have methanol gas and liquid ethanol. Option A is the only option that states this fact. The other options are incorrect.

The Boiling Point of Methanol Is 65°C and the Boiling
